LIQUID-ELEVATING APPARATUS.

Application filed January 2. 1920. Serial No. 348.726.

To all w/lom it may com-cm:

lie it known that l,'ll(l')l) V. \ViLLis, a citizen of the limitedStates, residing at ()sw'e'gu, in the county of Kendall and State ofIllinois, have invented a new and useful Improvement in Liquid-ElevatingApparatoe, of which the following in a specificatioii.

My invention relates to in'iprovements in liquid-elevating apparatus,more particularly though not exclusively. for the lifting of water andof the type involving the use of a chamber adapted to receive the liquidto be elevated, in one of the cycles of the op cration, compressed airbeing then introduced into the chamber to force the liquid therein outof the chamber. in the other cyele of operation, these operationscontinir ingin alternation as the pumping eontinues.

My object. generally stated, is to simplify and render better adaptedfor use, apparatus of this type as hitherto provided. and render thesame positivn; in operation and capable of continuous action with themini mum danger of impairment.

Referring to the acconipai'iying drawings. Figure 1 is a view inelevation of apparatus constructed in accordance with ill) invention.showing the same as loaded in a well the walls of which are shown insection. Fig. 2 is a hroken. enlarged. vertical sectional view of thelower portion of the apparatus. Fig. il in a similar view of a detail ofa valve employed. Fig. 4 is an enlarged view in clcration. partlysectional. ol' the portion of theapparatusshown as ahovc ground inFig. 1. the valve device therein shownheiug in the position it occupiesduring the sup plying of air-pressure to the htting evhndcr.

Fig. (l is a similar view of the valvc-niecl anisin referred to showingit in the positiou it occupies during the operation of the i'elilling ofthe lifting cylinder with the liquid to he lifted.

in the preferred; illustrated. cnihmlimcnt of Ill in vention. I employ acylinder T which is located in the rccc itaclcl rom which the fluid. asfor example. water. is to he hit ed. the cylinder T being shown asHippoi'lcd at a foot Bpn the bottom of a well rcp -i Specification ofLetters Patent.

The lower ends of the rods 44 areconnected with a disk 4.5 which surrounds the cylinder 37 and isslidable up and down thereon, this disk containing an opening throughwhich an upwardly extending rod 46 connected with the valve deviceformed of the stem portion 26 and heads 27 and 28, slidingly extends.The rod 46 is provided beneath the disk 45 with a shoulder portion 47.in the form of a nut, and at its upper end is equipped with a tappet 48.a coiled spring 49 surrounding the rod 46 and resting upon the disk 45for the purpose hereinafter described.

The disk 45 is provided with an upwardly extending spring arm 50 and adownwardly extending spring arm 51, which are secured, as by screws52.nnd 53. to brackets 54 and 55. respectively. carried by the disk 45,to extend at their cnds represented at 56 and 57. and preferablypresenting the converging surfaces as shown. into engagement with theouter surface of the cylinder 37 along which they move in the movementof the disk 45. as hereinafter described. The brackets 54 and areprovided with adjusting screws 58 and 59 which bear against the springs50 and 51. respectively. serving to place them under tension. Thesprings .31" and 57 cooperate with means. located adjacent the ends ofthe strokes of the disk 45. for presenting an overcomable resistance tothe movement oi" the disk 45 and the parts connected therewith. thesemeans in the arrangement shown being. at the uppen end of the cylinder.presented by the downwardly extending flanged portion 60 of the cylindercap forming the upper end of the cylinder. and at the lower end of thecylinder being formed of a boss (d on tln wall of the cylinder. theportions (it) and (ii being so located that they will be engaged by therespective spring arms 50 and 51 before the disk 45 reaches the ends ofits strokes. and in the final movement of the disk these arms will movebeyond the parts (1) and 61.

The valve 24 comprises a casing 62 se cured upon the upper end of a pipe63 which opens into the pipe 23. through the coupling (34. The casing 2contains a port 65 surrounded by a scat 6t; with which coiiperatcs avalve proper 67 having the stem portion (2* which slides in bearings (39and 70 in the casing 62. this valve closing in an upward direction andpreferably having a weighted part 71.

The operation of the apparatus is as follows: Assuming the apparatus tobe in the condition rspresented in Figs. 1 to 5. inchn sive, of thedrawings, compressed air passes through the pipe 32, port 29 of thevalve casing 25 thence through the port 30 and pipe 23 into the upperend of the cylinder 7 wherein it operates to force the water in thecylinder 7, which entered the latter the parts connecting the latterwith piston I 38, upwardly. As the parts inst described near the end oftheir upwar stroke. the spring 49 engages the tappet 48 and the springarm 56. the projection 60. the upward movement of these movable partsbeing thereby temporarily arrested by 'the resistance afforded betweenthe spring arm 50 and the projection 60. untilthe pressure against thebottom of the piston 38 overcomes this resistance. whereupon the arm 50swings outwardly out of engagement with the portion (30 thus causing thepiston 38 and the parts connected therewith to be rapidly impelledupwardiy. the valve comprising the heads 27 and 28 in this movementbeing shifted through the engagement of the spring 4!) with the tappet48. to the position. shown in Fig. 6 in which the head 28 extends whollyabove the port 30 and a disk T2 secured to the lower end of the stem 26moves against the bottom edge of the cylindcr .25. which is pressed asindicated at T3. The movement of the valve to the position as statedopens-the interior of the cylinder 7 and the cylinder 37 to theatmosphere through the port 30. valve casing 25 and port 73 therein.permitting the air from these cylinders to vent. whereupon thc i re"sure of water in the well and surrouadmg the cylinder 7. forces thevalve l5 upwardly and the cylinder 7 becomes charged with water to beexpelled therefrom in the next operation of the apparatus. As the piston38 nears the limit of its downward movcment. the spring arm 51 engagesthe projection (ll operating to pri'iducc the overcomablc resistance asexplained in the upward movement of the piston which is overcome by theweight of the piston and the parts suspended therefrom. after a shortpause in the dmvnward movement of the piston and until the air pressurebelow the. piston drops to a degree where it is overcome by the weightof the parts stated, the piston 38 in its final downward movementforcing the valve comprising the heads 27 be such that as soon as thepressure in erted by the land being lifted.

" and 28, by the engagement of the disk 45 with the shoulder 47 of thestem 46. to the position shown in Fig. 4. whereupon rompressed air againenters the top of the cylinder T to force therefrom the water in thiscylinder as hereinhefore explainvd. it heing understood that the partsare so proportioned and arranged. by preh-renre. that the valve formedof the hrads 27 and 28 is moved to a position in whirh air enters thecylinder 7 through the pi po 23 innnelhatch. upon the cylinder 7becoming charged with water. and this valve moves to the position shownin Fig. 6 immediately upon the rompletion of tho water-liftingoperation.

The valve device 2.4 is provided for the purpose of aiding in theventing of the uylinder T. following, the o 'ieration of fora-m thewater out of the cylinder T. Tho wright of the movable parts of thisvalve would ilw pipe 23, between the casing and the r vlinder 7, dropsby reason of the moi-rinent of the valve to the position shown in Fig.(9. it will automatically open and aid in the venting of this portion ofthe pipe 23. hot will quickly close as soon as the valve formed of theheads 27 and 28. moves to the position shown in Fig. ll to preventusrjapo oi air from the pipe :23 in tho water-lifting operation. Theprime purpose of the valvr 24 is to oven-nine the necessity of mailingthe pipe of large internal diameter to overeonie the resistance to theflow o1 airpressure therethrough. as wonlddie nei sarv where the pipe2Z3 is provided of a long length.
